Deep dive into the technology behind RCS_

Two-factor authentication (2FA) and one-time passwords (OTP) are cornerstones of modern digital security. Yet most companies still rely on traditional text messages, a channel increasingly plagued by ”smishing” (SMS fraud), spoofed sender names, and unnecessary friction for the user. As mobile communication is now modernized with RCS (Rich Communication Services), authentication flows are becoming more sophisticated and efficient.

Building customer journeys with rich media, carousels, and interactive buttons in RCS provides higher engagement than ever before. But in a reality where mobile data coverage may temporarily fail, network timeouts may occur, or the recipient’s device lacks RCS support, high demands are placed on delivery reliability. The solution is intelligent SMS fallback logic – built directly into the API infrastructure. With

For decades, SMS has been a reliable, but extremely quiet, channel. You send a message and you (hopefully) receive a delivery confirmation (”Delivered”) from the operator – but afterwards it’s a ”black box”. Has the customer actually opened the message? Are they responding right now? With the older SMS technology, this is completely missing.

The way companies communicate with their customers on mobile is undergoing a crucial transformation. Where text messages were previously limited to simple characters or heavily compressed MMS, today's customer journeys require crisp images, instructional videos, PDFs, and contact cards that can be saved with a single click. For over two decades, MMS has been the primary

Mobile communication has long been centered around simple, text-based senders. For the end user, this often involves uncertainty, forcing them to rely on an anonymous virtual number or an unverified text sender. As the next generation of mobile messaging, RCS (Rich Communication Services), is being rolled out on a broad front globally, it introduces

In previous articles, we have gone through the journey from SMS to RCS, the Universal Profile, architectural differences, and how we build visual carousels, now it is time to look at how we actually get the user to do something. With Suggested Actions & Replies, we take the step into pure interactivity. This is how
